Note
For the measurement of currents, the current transformer module CM-8820 is to be connected ahead of
AI-8510. The specification for the connection cable can be found in section
Danger
The connectors X1 and X2 may be detached or attached in de-energized state only!
The connector X1 must always be plugged during operation (even if no current measurement is used)!
Warning
The inputs of connector X1 must not be connected directly with a mains supply circuit!
The inputs of connector X2 may be connected directly with system current circuits up to AC 240/415 V.
Higher voltages must be adapted via interconnected voltage transformers!
Note
Take account of the direction of current flow when connecting the current measuring inputs. With inverse
connection, the measured values are inverted and receive a negative sign.
The same applies correspondingly for the voltage measurement (direction and phase angle).
